BASPI forms built in

BASPI forms built in

The Buying and Selling Property Information (BASPI) has been designed by the Home Buying & Selling Group to act as a key vehicle to collate and share forward all the required upfront information about the property.

Seen within the industry as being a ‘true source’ of information, our system has digitised the format to reduce duplication and ensure compliance with the Consumer Protection from Unfair Trading Regulations.

With Inventory Base, the BASPI makes the collation of information easier for estate agents, feeding into the TA 6 to help conveyancers progress the property quicker, preventing additional queries or delays to the transaction.
